New to the DDC here...
This is our 4th kiddo and we've used cloth dipes with all of them - we started when our oldest was around 6 months. We did mostly all pockets with him, but with each kiddo, we've moved to more and more only using prefolds/prefitteds and covers. I just went through my cloth yesterday and realized that I didn't really buy any new diapers (maybe one or two pockets) with my #3 kid, and with this new baby, I am all set. I have prefolds and covers that are 8 years old and are just now wearing out - so I think the $ savings REALLY comes when you are able to reuse the diapers with multiple kids.
I know a few people who use prefolds at a laundromat and don't have any problems. They are workhorse diapers - you don't have to worry as much about things causing buildup, etc. In fact, I don't use any special detergent or anything for my diapers or my baby clothing - it all gets washed with the same detergent (which varies from Tide to Arm & Hammer)
I might pick up some prefolds and covers - you could get a dozen prefolds and 2 covers for pretty cheap, and that would be fine for a day. Then, perhaps do a mix of disposables as well as cloth diapers and see if going to the laundromat every 3 days is that much of a pain or not. Honestly, our babies did not add that much to our normal laundry (excluding the diapers).
I would not go the G-Dipe route if you are planning on flushing - those are really hard on the plumbing and clogged when we tried them out. We were concerned with the giant bags of trash we were accumulating when we used dispoables with our 1st son which is why we made the original switch to cloth (although we have consistently used disposables at night for our heavy wetters to minimize waking up and increase sleep ;) That only amounted to about $7/month though for what we used.
